在 MATLAB Online 中打开

You can receive data from com port (Serially). Use This Command

    Ser_Obj = serial();   % Serial Communication Object (Default Setting) % 
for i = 1 : 1024          % for 0 - 1023 decimal received %
    fscanf (Ser_Obj);     % for receiving data %
end
The formt of fscanf is given by (you can see on Matlab help)
    A = fscanf(fid,format)
   [A,count] = fscanf(fid,format,size)

and if you want to do in GUI then Make a GUI file and take a push button and write this code in push button. Doing this when you press the push button then you receive data.
